LIACHINE FOR MAKINGCAPS Application filed December e, 1928; SerialNetti-4,193, and in Sweden November 11 1927.

This invention refers to means for crisping or crimping the tongue inmetallic caps for bottles in which the tongue extends from the rim ofthe cap.

5 The invention is illustrated in the accompanying drawing, where Figure1 is a perspective view of a cap according to the invention; I

Figure 2 is a vertical section of a stamping 6 vtool for performing thecrisping, the said tool being here shown combined with a tool alreadyknown for inserting packing in the finished cap;

Figure 3 is a N matrix;

Figure 4 shows the stamp from the under side; and

Figure 5 shows the combination used in such capping machines in whichthe cap is pneumatically conveyed from tool to tool.

In Figure 1 the cap tongue at is crimped orcrinkled. The crimping may beeffected by different tools but itlis most suitable to use a stampingtool, that is to say, a stamp 25 with matrix. According to theinvention, the said two parts are preferably combined with a tool bywhich the cap is treated, for instance, with the tool for insertingpacking in the cap, as shown in the drawing.

The construction of the said tool being already known the drawing onlyshows so much of it as is necessary for rendering theinvention clear.The main parts of the said tool are the reciprocating shell or upperstamp 1 movable up and down, and the lower stamp plan View of thestamping or rod 2 also movable up and down in a sleeve 3 of the fixedbed or machine table 4:. The stamp 1 goes down to the said sleeve ustafter the cap advances under the stamp, whereby the cap becomes locatedin the hollow or female section of the stamp. Simultaneously a cork-leaflaid over the rod 2 is pushed into the cap by the rod. The cap is thenpushed out from the, stamp 1 by a small rod 5. Figure 2 shows a cap bydot-and-dash lines on its way in under the stamp 1. The parts mentionedabove are already known and, consequently, the construction and theoperating manner of same need not be described more closely.

According; to the invention the is now shaped as a crimping stampalso'and has at its one slde an enlargement or swell 7, the lowersurface of which is crispy and I forms the working surface or malesection cooperating with a corresponding surface or female section ofthe matrix 8.' The cap will 7 be located under the stamp in such amanner fected at the same time as the packing is in-. serted, that is tosay, these two operations are made in a single step.

In the machine shown in Figure 5 the crimping stamp is combined in thesame manner with the toolfor inserting the pack In this machine the capis moved from a stamping and bending tool located at Z) where the cap ismade, to the tool 1, 2 (Figure 5 only shows the lower stamp 2) andfurther to rotating nozzles located at 0 where the capping is effected.The movement of the cap is effected by means of an air current from anozzle 13 in a tube for pressure air. 10 is a conveyer, for feedingcork-leaves to the tool. 9 is one half of a channel in which the cap isconveyed from tool to tool. Concerning the suitable position of the capfor beinginserted in the nozzles the cap tongue a may be directedbackwards in relation to the conveying direction and the crimpedsurfaces may of course be located on the side not facing the nozzles.cap may not stick when it is to be moved by the air current from thesaid stamps 1, 2, the working surface of the lower stamp 2 may, on thisoccasion, he on a level with the working surface of the crimping matrix8, the stampbeing maintained in this positionuntil the cap has passedover it.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is: i

1. In a device of the characterdescribed,

a packing inserting and crimping tool for tongued caps, comprising areciprocating shell provided with the female section of the packinginserting tool and the male section of the crimper, a fixed bed havingan opening registering with the female section of the 'as to allow thetongue to be placed between I the said surfaces, the cri'sping beingthen ef- 7 I In order that the 7 ice y n 1 the tool; i r j r v I 3. Adevice as claimed in claim 1, in which the female section of the crimperis disposed 4 reached by the Working face "of the lower-I I packinginserting tool andthe female section of the crimper disposed marginallyof the opening, and a lower stamp forming themale section of thepackingmember reciprocally mounted in the opening.

2. A device as claimed in claim 1,"in which the crimping portionofthetool is formed on an elevation substantially the same as that stamp inits uppermost position.
